Definitions

  • Ceramic sealing disks above for use in sanitary mixing faucets are widely used and are described, for example, in EP-A-43 456. According to this disclosure an aluminum oxide having a 3 to 25 wt.-% zirconium dioxide content is proposed as the material. With the known sealing disks a reduction of the displacement forces was already achieved, and despite an exceedingly low profile bearing of 10 to 40% an adequate sealing action could still be achieved.
